ner to form a unit from which all the carbon sheets are removable by a single operation. Such manifold books areof special advantage when used for recording transactions of sale and delivery of merchandise when the recording is done by the person having charge of such delivery, for instance the driver of a commercial vehicle.

The object of the invention is to provide a manifold book unit comprising a plurality of form sheets interleaved with carbon sheets so arranged that all .the carbon sheets may be removed by a single operation. Incidental objects will appear as this specification proceeds. Ac cordingly the invention is embodied in a manifold book arranged and constructed as herein after set forth and as illustrated in the accom panying drawing in which Fig. 1 is a perspective view of a manifold book unit embodying the invention.

Fig. 2 is a similar view but showing the carbon leaves separated and partly removed.

7 Fig. 3 is an edge view of a manifold book showing one unit removed.

Fig. 4 illustrates how the removal of the carbon sheets may be practiced; a

Fig. 5 is a detail view.

Referring to Figure 1 of the drawing the reference numeral l0 denotes a single unit in the improved manifold book. The unit consists in this instance of four form or record sheets I I, I l and three interleaved carbon sheets l2, [2. The numstaple l5 which is positioned within a severable. thumbpiece portion I6 surrounding the staple.

This portion is almost completely severed from the form sheet by a circular cut I! and two short weakened lines 18, I8. The line His cut through the paper and connects with the edge I4 by said weakened lines. Thus the severable portion [5 may be entirely removed-from the sheet by tearing along the two short weakened lines I8. The

.severable portions of the form sheets are of course in superposed alined registering positions as will be understood. v

The carbon sheets l2 are shorter in one direction than the form sheets ll so that there is left a gripping portion or strip l9 at the one end of the form sheets which may be seized without seizing the carbon sheets. The gripping portion is preferably at the edge opposite to the severable portions It. The units are preferably assembled into a book as seen in Figure 3 where the numeral 5 20 indicates the units. In order to remove a unit y from the book, the form sheets have av weakened line at 2| so that the portion 22 of the sheets beyond the weakened line 2! forms a stub.

The unit is used as follows: The required num- 10 her of form sheets I l andcarbon sheets !2 are interleaved and secured together by the staple IS, the form sheets having previously been provided with the weakened lines 21 and the severing cut I! as well as the short weakened lines l8. The 5 taches a unit from'the book, if a book has been 25 formed, by tearing along the weakened line 21, see Figure'B where the top unithas been torn 011'. Next he seizes the unit as shown in Figure 4. With his left thumb and forefinger he takes hold of the portion IQ of the form sheets, not seizing 39 the carbon sheets. With his right thumb and forefinger he seizes all the sheets, placing his right thumb right upon the severable portion l6 in' the original sheet, hence upon all the severable portions of theform sheets. He then bends the 5 unit slightly between his hands and then with a quick snapping action moves his hands apart and removes all the carbon leaves by tearing the sev- 'erable portions 16 of! the form sheets and completely' removing the carbons.

40 Theoperator then has the form sheets together in his left hand and the carbon sheets in his right hand, the carbon sheets being fastened together with the severable portions l6. He may then distribute the original and copy form sheets as 4,5

wanted, whileihe carbon sheets may be discarded.

It has been found that manifold book units embodying this invention may be inexpensively assembled and put together to form a. book of many units ready for convenient use in recording a 5g transaction. The assembling of the units into a book or pad is an inexpensiveand convenient method of providing a supply of units. It will be noted that the construction includes several substantial advantages. The fact that all the ItiS 2o leaves are secured together at one end and that the form sheets are preferably secured together at the opposite end insures perfect alinement of the forms and. that the carbon sheet will not creep or become displaced. The severable portions :at

the lower ends of the form sheet provide a good gripping portion thereof and at the same time insure quick and clean severance.

When a number of units are secured together in a pad by pasting or otherwise as indicated at 25 in Figure 3, the fact that the opposite ends of the sheets in a unit are secured together by the staple l facilitates the division and separation of the units in that by running a finger across the stapled ends of the pad, the uppermost unit is easily lifted away from the other units in a manner easily understood.

Although the drawing illustrates the invention in its preferred form it"will be understood that changes and variations may be made and devised without abandoning the main idea of the invention. For instance the shape of the thumb pieces l6 may be other than as shown and they may be located at any point on any of the unsecured edges of the unit as may be desired or ata corner thereof. Units may be placed loosely within a binder or the like, or they may be assembled into a pad by gluing or stapling.

I claim:

1. A manifold book unit comprising an origina sheet and a copy sheet of the same size in superposed relation, a carbon sheet between the same, said original and copy sheets having each a superposed alined transverse weakening line spaced a distance from one of their edges, said carbon sheet between the other said sheets having its one edge alined with the alined edges of the other sheets reniote from said weakening lines, said carbon sheet extending between said other sheets to within a short distance of said weakening lines, means for securing all of said sheets together at a portion of oneoftheir edges and means for securing only 5 the original and the copy sheets together along the opposite edges. 4

2. A manifold book unit comprising an original sheet and a copy sheet of the same size in superposed relation, means for securing said sheets to- 10 gether at one of their edges, superposed alined transverse weakening lines in said sheets spaced a distance from said secured edges, a carbon sheet between said sheets, said carbon sheet being of the same width as and shorter than the other two sheets and-terminating a distance from said weakening lines, and a staple passing through all of the said sheets for securing them together in permanent relation, said staple being located adjacent the edges of all the sheets opposite to the secured edges of the original andthe copy sheets.

3. A manifolding book comprising record sheets and carbon sheets in superposed relation, means for securing all of the record sheets together at one edge thereof, asingle superposed alined transverse weakening line in each of said record sheets .spaced a distance from the secured edges of said sheets, the said carbon sheets being shorter than the record sheets and terminating a distance from said weakening lines in the record sheets and stapies for securing selected numbers of the record sheets and the carbon sheets together in permanent relation, said staples being located adjacent the edges of all the sheets opposite the secured edges of the record sheets. 0
